POWER-FEED OIL-DROPPER.

Specification of Letters Patent.

Patented July 25, 1916.

Application filed J'une2, 1915. Serial N 0. 31,762.

To all whom it may concern Be it known that I, ANDREW OTIS JAoK- son, a citizen of the United States, residing at Corvallis, in the county of Benton and State of Oregon, have invented certain new and useful Improvements in Power-Feed Oil-Droppers, of which the following is a specification.

This invention provides a lubricator of the type adapted to supply oil in measured quantity and at regular intervals and which is positively operated from a moving part of the machine or mechanism to which the lubricator is applied.

The invention, furthermore, provides a luhricator embodying a sight feed so that the operation may be observed at all times, such lubricator providing for regulating the feed, first by varying themovement and second by adjusting the size of the pocket or oil receiving cavity.

The invention also aims to provide a .lubrieator of the type hereinbefore stated which admits of the parts being readily, assembled or separated as may be required, hence inspection may be easily made and replacements effected at a minimum cost.

when required.

With these and other objects in view,

which will readily appear as the nature oftions within the scope of the invention as.

claimed may be resorted to when desired. Referring to the drawings, Figure 1 is a view in elevation of a positive sight feed lubricator embodying the invention; Fig. 2 is a front view of the lubricator; Fig. 3 is a sectional detail on the line 33 of Fig. 2; Fig. 4 is a sectional detail on the line 4.-l of Fig. 2; Fig. 5 is a detail view of the plug valve, a portion being broken away to show more clearly the adjustable 'oil pocket or recess.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by thesame IQT'QIGHCG characters.

The numeral 1 designates a stationary part, such as a steam pipe which is illustrated as forming a convenient support for the, lubricator.

. The numeral 2 indicates a moving part of the machine or mechanism to which the lubricator is fitted, such part representing the rod extending from the cut-off of the engine. It is to be understood that the lubricator may be attached to any part of the engine and the operating member may be connected to a relatively moving part so as to positively actuate the lubricator.

The lubricator embodies a casing 3 and a valve i, the latter being of the plug type and tapering throughout its length so as to maintain a close joint within the valve casing. The smaller end of the plug valve is formed with a stem 5 which projects beyond the casing 3 and is threaded to receive an adjusting nut 6. An expansible helical spring 7 is mounted upon the stem 5 and is confined between the nut 6 and the casing 3 and normally exerts a pressure upon the valve to hold the same within the casing 3. The valve 4 is also formed at its larger end with a stem 8 having an enlargement 9 upon which an arm 10 is loosely mounted. A ratchet wheel 11 is secured to the stem 8 of the valve and its teeth are adapted to be engaged by means of a pawl 12 which is pivotally mounted upon the arm 10. The arm 10 is adapted to have an oscillatory movement imparted thereto from a moving part of the machine or mechanism to which the lubricator is fitted. In one movement of the armlO the pawl 12 rides upon the teeth of the ratchet wheel 11 and in the opposite movement of the arm 10 the pawl 12 engages with a tooth of the ratchet wheel and turns the latter and thevalve 4,,thereby effecting a positive feed of the lubricant. A stop 13 projecting from the casing 3 engages the arm 10 tolimit the movement thereof in one direction. A spring 14; normally exerts a pressure on the arm 10 to yieldingly hold the same in engagement with the stop 13. The spring 1d preferably has one end attached to the stop 13 and extends around the hub of the arm 10 and engages the latter so as to press the same against the stop 13; The arm 10 is moved against the tension of the spring 14: and when released the spring 14 returns the arm 10 to the predetermined position.

The valve 4 may be provided with any number of oil pockets, recesses or cavities, as indicated at 15 and 16. These oil pockets may be of fixed capacity or may be adjustable. When the oil pockets are of fixed size they deliver a like amount of oil at each charge but the interval of delivery may be 5 regulated by varying the movement of the arm 10. When the oil pocket is adjustable, as indicated at 16, a plug 17 is threaded into the pocket and may be moved so as to regulate the capacity and likewise the amount of oil to be delivered at each charge.

The valve casing 3 has an oil inlet 18 and an outlet 19. A passage 20 formed in the inner wall of the casing 3 is in communication with the outlet 19 and is of sufficient size to insure the draining of the oil from the pockets 15. Oil may be supplied to the lubricator from a suitable source by means of a pipe 21 and may be conveyed to the part to be lubricated by means of a pipe 22, each of such pipes being provided with a valve for cutting oif the fiow when required. A plug 23 is fitted into the outlet 19 and is formed with a nozzle 2 1 from which the oil drips. A sight feed is interposed between the outlet 19 and pipe 22 and consists of a glass tube 25, the same being confined between the plug 23 and a corresponding plug 26, each of such plugs being flanged to center and retain the glass tube 25 in place. A bracket 27 forming a part of the valve casing receives the plug 26 and forms a support therefor. The delivery pipe 22 has connection with the plug 26.

A guide 28 is secured to the moving part 2 by means of a clamp 29 and receives a slide 30 which is connected with the arm by means of a rod 31 and yoke 32, the latter having adjustable connection with the rod. A set collar 33 adjustable upon the guide 28 is adapted to engage the slide 30 and move the same forward toadvance the valve and eifect delivery of the oil. The return movement of the arm 10 is efiiected by means of the spring 1 1. By proper adjustment of the set collar 33 which acts as an adj ustable' stop the movement of the slide 30 and valve may be regulated so as to vary the intervals of discharge of the lubricant.

It is to be understood that the valve may be adapted to supply lubricant to different parts and also that the amount of lubricant to be delivered at each charge may be regulated. As indicated a clamp 33 serves to secure the lubricator to the fixed part 1, but it is obvious that any attaching means may be employed for securing the lubricator to a suitable support.

Having thus described the invention, what is claimed'as new is 1. In a lubricator, a casing having an oil inlet and an oil outlet, a'plug valve fitted within the casing and having an oil pocket, a ratchet wheel secured to the valve, a pivoted arm, a pawl mounted upon the arm and adapted to engage the teeth of the ratchet wheel, a stop for limiting the movement of the arm in one. direction, a spring yieldingly holding the arm in engagement with the stop, a reciprocating member, and an adj ustable connection between the reciprocating member and pivoted arm for varying the movement of the latter and thereby regulating the feed of the oil by governing the frequency of the oil discharge.
